The TOOLTOP ET2202 is a smart battery analyser for 12V and 24V lead-acid batteries in cars, trucks, generators and UPS/solar banks. Clip it on and it measures internal resistance, cold-cranking amps (CCA 100 to 1999) and state of health, so you can tell a weak battery from a good one before it fails.
It also runs a vehicle cranking (starting) test, a charging-system test, a load test and battery temperature measurement with the included probe. It supports STD, AGM, GEL and EFB batteries and EN, IEC, SAE, DIN and CCA rating standards, using a four-wire Kelvin connection for accurate readings.
